The study is designed to evaluate the safety and efficacy of Actelion-1 in delaying disease progression and mortality in patients with pulmonary arterial hypertension (PAH). The SERAPHIN study is a global study and will enroll more than 500 patients from at least 180 centers, randomized 1:1:1 to receive two different doses of Actelion-1 (3mg and 10mg once daily) or placebo. The centers represent over 40 countries in North and South America, Europe, Asia Pacific and Africa.
Jean-Paul Clozel, CEO of Actelion, said: “Actelion and Tracleer have revolutionized PAH therapy. A large number of supportive studies in many PAH sub-populations, together with a first-in-class educational marketing approach, have made Tracleer the cornerstone of therapy in PAH.”
